Product Desciption
We are a professional producer and major manufacturer for rock drilling tools, whom are capable to design and manufacture according to customer's requirement on the Bit Dia\No., Air holes, carbide button shape and the bit face shape. High air pressure and low air pressure.
Thanks to our long year experienced technicians and engineers in the field for more than 15 years, whom make this into reality and meet the clients' demand accurately.
All hammer and bits are compatible with many products manufactured by Sandvik, Atlas Copco, etc, all our products are widely used in mining, tunneling, quarrying, construction, and civil engineering project.
Our advantage and strongpoints:
1. Customized acceptable
2. Raw material is very high quality alloy metal, we focus on quality and care clients' concern.
3. Harden treatments
4. Full production procedures by our own factory from raw material cutting, hot forging, milling, plane, grind till pack for delivery.
Informations for a quick and accurate offer:
1. Advise us bit diameter, face shape
2. Advise us Carbide button shape
3. Advise us qty of air hole
4. Advise us the rock formations situation, we could assist and give a suggestion on the above.
5. Advise us the drilling hole diameter, we could assist and suggest a solution.

Products:
Bit face shape options:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Carbide button shape selection:
1. Domed/Round Button
Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for every abrasive and very hard formations.
2. Parabolic/Semi-Ballistic Buttons
Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
3. Ballistic Button
Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and mesium hard formations. They can also be used as gauge buttons if the rock is soft.
4. Sharp Button
Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible.
5. Flat Button
Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
Production Corners:
